ERROR_TOO_MANY_SEMAPHORES

Error code 100 is usually a symptom of another error and not an indication of the error itself. It is described as a catch all error, meaning the system may not like or understands what has just been said, so an error code will result.

It is usually received by a device that is remote within an ISDN chain connection. This error is caused by a switch occurring error or one detected downstream of an orbitor. When the orbitor has not made any correct calls to date, an erroneous number may be the reason or the number being called is actually invalid. To contact the remote destination, verify the true ISDN number is being dialed.

When the orbitor logs on to a seemingly proper connection then disconnects with error code 100, the message is of no consequence and is a sign of the disconnection timing the switched network of the ISDN. It means that an error was logged during a call’s disconnection. Some reasons as to why this happens may be there might be a disconnection and termination at the ISDN call’s one end, while the other is propagating data still. Once this data is received at the disconnected end, it may generate error code 100. When trying to investigate the reasons behind the premature termination of the connection, the answer will be the target call’s premature disconnection. There are a number of reasons for this, but the two main ones are PPP NCP.LCP negotiations failure or Password verification failure. One can contact the destinations router’s administrator, at the same time review the profile of the orbitor’s Remote Site’s configuration, for errors that are glaring.

Various interface or line faults can result in faults in the teardown or setup, but more often then not this is not the cause when receiving the ERROR_TOO_MANY_SEMAPHORES message. Should the above fixes fail to bear fruit, contact the PTT or Telephone Company so they can diagnose the fault and look into which is the error prone component. They should be able to isolate the device in particular that is failing, through its causes, which would be performed on the interfaces and line.

This error typically goes unnoticed and is rather common. The most obvious would be a app server was forcibly shut down while there was a connection by a jolt client. It can also be caused by running short of sockets on a server; it is therefore advised that one checks their file descriptor numbers featuring ulimit.
